Tacit coordination in monozygotic twins, dizygotic twins and virtual twins: Effects and implications of genetic relatedness

Game theorists have long been interested in why some partners are more successful at achieving mutual goals than others. The present study was conducted to determine if tacit coordination (non-negotiated consensus) varies as a function of genetic relatedness between social partners. The sample included 7–13-year-old monozygotic (MZ) twin pairs (n = 53), dizygotic (DZ) twin pairs (n = 85) and virtual twin (VT) pairs (n = 42; same-age unrelated siblings). Co-twin agreement on questions completed under individual and coordination conditions was compared across the three groups. MZ twins showed significantly greater overall agreement than DZ twins and VTs, using multiple criteria. The implications of these findings are considered with reference to behavioral-genetic and evolutionary theories of behavior.

Interactive Genetic Counseling Role-Play: A Novel Educational Strategy for Family Physicians

Background Family physicians (FPs) are increasingly involved in delivering genetic services. Familiarization with aspects of genetic counseling may enable FPs to help patients make informed choices. Purpose Exploration of interactive role-play as a means to raise FPs’ awareness of the process and content of genetic counseling. Methods FPs attending two large Canadian family medicine conferences in 2005 were eligible—93 participated. FPs discussed a case during a one-on-one session with a genetic counselor. Evaluation involved pre and post intervention questionnaires Results FPs’ baseline genetic knowledge was self-rated as uniformly poor. Baseline confidence was highest in eliciting family history and providing psychosocial support and lowest in discussing risks/benefits of genetic testing and counseling process. Post-intervention, 80% of FPs had better appreciation of family history and 97% indicated this was an effective learning experience. Conclusions Role-play with FPs is effective in raising awareness of the process and content of genetic counseling and may be applied to other health disciplines. This research was funded by: The Canadian Institutes of Health Research (CIHR) Institute of Genetics, The Genetics Education Project (funded by the Ontario Women’s Health Council), and GeneSens (funded by a CIHR Interdisciplinary Capacity Enhancement Team Grant).     

Adult helping qualities preferred by adolescents

Most studies of therapeutic alliance have focused on adult populations and been written from the therapist's perspective. Thus, there is a clear need for studies of therapeutic alliance that focus on adolescent populations from the perspective of the adolescents. The current study is an exploratory process investigation using a focus group methodology with a nonclinical sample of adolescents to determine which traits in adults might foster alliance, with the assumption that the same traits would apply to therapeutic settings. A content analytic approach was used and 12 adult qualities found to be preferred by adolescents from most to least cited were: respect, time shared, openness, role characteristics, recognition, guidance, identification, trust, freedom, like/ dislike, responsibility, and familiarity.     

Evolution of the Colored Eco-Genetic Relationship Map (CEGRM) for Assessing Social Functioning in Women in Hereditary Breast-Ovarian (HBOC) Families

The CEGRM was initially conceived as a simple, concise, visual representation of the social interaction domains of information, tangible services and emotional exchanges (Kenen, R., & Peters, J. (2001). J Genet Counsel, 10, 289–309). A blend of the genetic pedigree, genogram, and ecomap, the CEGRM was developed to facilitate contemporary genetic counseling goals. An exploratory pilot study of 20 subjects showed that it was feasible, comfortable and efficiently accomplished, and that the process was useful both for assessment and as an intervention with study participants (Peters, J. A., Kenen, R., Giusti, R., Loud, J., Weissman, N., & Greene, M. H. (2004). Am J Med Genet Part A, 130A, 258–264). Subsequently, we have extended the CEGRM to 150 women from hereditary breast/ovarian cancer (HBOC) families; three different investigators have successfully administered this tool. The preliminary findings from the exploratory study were confirmed in the larger sample. Engaging in the interactive, insight-promoting CEGRM process provides a novel tool for assessing the social context of genetic testing, and helping high-risk women better understand and integrate genetic information into their personal and family identities, health beliefs, and decisions.     

Recollection in an episodic-like memory task in the rat

Episodic memory in humans is the conscious recollection of a past event. Animal models of episodic-like memory assess the memory for "what"happened, "where" it happened, and either "when" it happened, or in "which" context it happened, although recollection on such tasks is often difficult to measure. Here we present the first evidence of successful recollection of a past event in a rat in a task which is easily performed, requires little training, and is easily adaptable for other commonly used laboratory species.     

Beyond "healthy eating" and "healthy weights": harassment and the health curriculum in middle schools

In this paper we use data from interviews conducted with grades 7 and 8 girls to explore connections between body-based harassment and girls’ body modification practices. We discuss how the elementary health curricula fail to consider harassment and other cultural factors that influence the body modification practices and eating patterns of diverse girls. More specifically, we argue that the “healthy eating, healthy weights” approach of the grades 7 and 8 Ontario health curriculum has five limitations: (1) it sends contradictory messages; (2) it increases anxieties about body weight; (3) it ignores the multiple causes of eating problems; (4) it marginalizes issues most relevant to racialized girls; and (5) it ignores dilemmas associated with physical development. We conclude with suggestions for developing a curriculum on body dissatisfaction and eating disorders prevention that considers the various socio-cultural factors influencing the range of body monitoring and modifying practices taken up by girls.     

Changes in Jail Inmates’ community connectedness across the period of incarceration

ABSTRACT

Jails bring inmates into proximity with one another and separate them from the community. Because inmates’ connectedness to one another and to the community influences post-release functioning, understanding risk factors for maladaptive shifts in connectedness may inform interventions. The current study examined changes in jail inmates’ (N = 203) connectedness to the community at large and to the criminal community, and predictors of individual differences in changes over time. Connectedness to both communities did not change on average during incarceration, but younger and less guilt-prone inmates increased more in connectedness to the criminal community than older and more guilt-prone inmates, suggesting connectedness interventions should target individuals exhibiting this constellation of attributes.     

Contact high: Mania proneness and positive perception of emotional touches

How do extreme degrees of positive emotion—such as those characteristic of mania—influence emotion perception? The present study investigated how mania proneness, assessed using the Hypomanic Personality Scale, influences the perception of emotion via touch. Using a validated dyadic interaction paradigm for communicating emotion through touch (Hertenstein, Keltner, App, Bulleit, & Jaskolka, 2006), participants (N=53) received eight different touches to their forearm from a stranger and then identified the emotion via forced-choice methodology. Mania proneness predicted increased overall accuracy in touch perception, particularly for positive emotion touches, as well as the over-attribution of positive and under-attribution of negative emotions across all touches. These findings highlight the effects of positive emotion extremes on the perception of emotion in social interactions.
